What are the common scanning methods of CMM

Coordinate Measuring Machine

has applications in many ranges, and can also measure many parameters of the workpiece. We know that the quadratic image measuring machine can also simply detect the three-dimensional parameters of the workpiece after the addition of the probe, then

CMM

In addition to completing the simple length, width and height of the three-dimensional measurement, but also on the workpiece's complex surfaces and other measurements.　　Coordinate Measuring Machine

In the measurement of some parameters of the workpiece, more often by scanning the workpiece, so as to achieve the purpose of measuring the workpiece, then

Coordinate Measuring Machine

Introduction of the workpiece since the mid-sixties, along with the advancement of computer technology and electronic control system, the development of detection technology, for the measuring machine to high precision, high speed direction provides a strong technical support.

CMM can be divided into contact measurement and non-contact measurement and contact and non-contact measurement, contact measurement is often used in three-dimensional measurement of machining products and compression molding products, metal film.

To contact

as an example to illustrate several scanning the surface of the object, in order to obtain the data point of several methods, the data point results can be used for processing data analysis, but also for reverse engineering technology to provide the original information. Scanning refers to the application of PC-DMIS software with the help of a measuring machine in a specific area of the surface of the object to be measured for data point acquisition. This area can be a line, a facet, a cross-section of the part, a curve of the part or a circumference at a certain distance from an edge. The type of scanning is related to the measurement mode, the type of probe and the availability of CAD files, etc. The status button (Manual/DCC) determines the scanning (SCAN) options available on the screen. If you are measuring in DCC mode and have a CAD file, the scanning options are OPEN LINEAR, CLOSED LINEAR, PATCH, SECTION and PERIMETER. If DCC is used and only wireframe CAD files are available, then OPEN LINEAR, CLOSED LINEAR and PATCH scanning are available. If manual measurement mode is used, then only the basic MANUL TTP SCAN method can be used. If in manual measurement mode, the probe is a rigid probe, then the available options are FIXED DELTA, VARIABLE DELTA, TIME DELTA and BODY AXIS SCAN.
